A personal floatation device on your vessel should be sized for which person on board?

A personal flotation device (PFD) on your vessel should be sized for each individual on board, taking into account their weight and chest size. It's essential to ensure that each person has a properly fitted PFD that is appropriate for their body type to ensure safety and effectiveness in the water. Additionally, PFDs should be readily accessible and in good condition for use by all passengers.
